Her body was found Wednesday in a landfill near the Mercer-Butler County line. Police said she was stabbed in the chest. One week into the investigation, police don't have new information about what happened.

"It is a little frustrating. We're out canvassing the area again today, trying to talk with neighbors again, friends family," said Chief Bob Gavalier of the Austintown Township Police Department.

Burger's mom, Jacqueline Bacher, can't wrap her mind around it.

"The thought, I mean, how many days did she lay in a landfill with garbage? And nobody cared that that's where she ended up?" Bacher said

Now, investigators want to talk to a teen named "James." They say he's someone who knew Gina and may be able to help

"We're checking with her friends. We're checking with social media, trying to get some type of lead on who can … at least seen her last," Gavalier said.

Police won't call "James" a person of interest. At this point, they say they have no leads on the case. That's tough for Gina's mom to hear.

"There are consequences for this," Bacher said. "You don't just disregard somebody's life and throw them in a trash bin and that's it and think you can live your life like nothing went on, because we're certainly not living our life like nothing went on now."

Police are hoping to get new forensic information into their office by the end of Monday that will help them with the investigation.
